Trying to find a generic TLD that is safe from the clutches of the proposed SOPA bill? Then you'll want one outside of the jurisdiction of the USA, but there's not much choice in terms of the home-soil locations of registries.

TLD Registry URL Registry Location
org Public Interest Registry pir.org USA
info Affilias affilias.info Ireland
mobi dotMobi mtld.mobi Ireland
aero SITA nic.aero Switzerland
me .Me Registry domain.me Serbia & Montenegro
biz Neustar neustarregistry.biz USA
coop Dotcooperation nic.coop USA
jobs Employ Media goto.jobs USA
museum MuseDoma about.museum Sweden
name Verisign verisign.com USA
pro RegistryPro registry.pro USA
travel Neustar neustarregistry.biz USA
tel Neustar neustarregistry.biz USA

I was surprised that the .info and .mobi gTLD registries are located in Ireland. I'd love a .aero but they are rather expensive.
